Try this: rrdtool create numUsers.rrd --step 300 DS:numUsers:600:0:U RRA:AVERAGE:0.5:1:300 # Daily, 1500 minutes, 1.04 days RRA:AVERAGE:0.5:7:300 # Weekly, 10500 minutes, 7.3 days RRA:AVERAGE:0.5:35:300 # Monthly, 52500 minutes, 36.5 days RRA:AVERAGE:0.5:360:300 # Yearly, 540000 minutes, 375.0 days
Put all that on the same command line (minus the comments at the end of each RRA line) and try that. That will give you a database with one Data Source (numUsers) and four RRAs: - One for Daily information, one data point every five minutes - One for Weekly information, one data point every 35 minutes - One for Monthly information, one data point every 175 minutes - One for Yearly information, one data point every 1800 minutes This closely mimicks the information that MRTG keeps. If you'd also like the maximum number of users, include these RRAs: RRA:MAX:0.5:1:300 # Daily, 1500 minutes, 1.04 days RRA:MAX:0.5:7:300 # Weekly, 10500 minutes, 7.3 days RRA:MAX:0.5:35:300 # Monthly, 52500 minutes, 36.5 days RRA:MAX:0.5:360:300 # Yearly, 540000 minutes, 375.0 days This information was pulled from the RRDTool rrdcreate.html manpage available with the package in the doc/ directory. -Mark nat wrote: > Hi all, > > I have downloaded the rrdtool from the website and successfully completed > the tutorials. > > I would like to use it to graph the amount of users signed up on our system > over time, I will update the database every 5 minutes. > > I presume a sample maybe: > > 15:05 - 6 users > 15:10 - 6 users > 15:15 - 7 users > 15:20 - 8 users > 15:25 - 8 users > <cont....> > 16:30 - 9 users > 16:35 - 9 users > 16:40 - 10 users > 16:50 - 11 users > <cont...> > 19:15 - 11 users > 19:20 - 12 users > 19:25 - 15 users > > etc..... > > theses values will allways be integers, and i understand how to run the > 'rrdtool update' command automatically every 5 minutes from a script.
